It seems that you're in Germany. We have a dedicated site for Germany. During the last decades the knowledge of the magnetic properties of the d transition elements and of their metallic alloys and compounds has increased widely. The improvement of preparation techniques for well-defined substances, the development of sophisticated measuring methods and above all the drive to obtain more insight in the origin of magnetic interactions in solids have resulted in the publication of many specific magnetic properties for an abundance of all kinds of metallic materials. It has been attempted to include preferentially those properties which are of a basic character and which therefore are most often needed by scientists active in the field of solid state magnetism.

Transition metal , any of various chemical elements that have valence electrons—i. While the term transition has no particular chemical significance, it is a convenient name by which to distinguish the similarity of the atomic structures and resulting properties of the elements so designated. They occupy the middle portions of the long periods of the periodic table of elements between the groups on the left-hand side and the groups on the right. The most striking similarities shared by the 24 elements in question are that they are all metals and that most of them are hard, strong, and lustrous, have high melting and boiling points, and are good conductors of heat and electricity. The range in these properties is considerable; therefore the statements are comparative with the general properties of all the other elements. Many of the elements are technologically important: titanium , iron , nickel , and copper , for example, are used structurally and in electrical technology.

Platinum Metals Rev. Well-marked magnetic properties are associated always with electrons in incomplete inner electron shells which maintain a comparatively localised and atomic character in the solid state - unlike the delocalised conduction electrons which become a property of the solid as a whole. There is not, however, an absolutely clear-cut division between localised and non-localised situations. The best example of the well-localised situation is provided by the incomplete f -electron shells of the rare earth metals. The 3 d electron shells of the first transition group metals especially manganese, iron, cobalt and nickel are not as well localised as the rare earth f -electrons, and in the pure metals strong direct interactions between d -electrons on neighbouring atoms are certainly present. We still do not know whether these direct interactions or indirect ones through the conduction electrons are dominant in providing the ferromagnetism of iron, cobalt and nickel. Palladium, at the end of the second transition series, is very nearly a magnetically ordered material, and small amounts of iron in solid solution produce a ferromagnetic moment which is not all provided by the iron atoms.

Голоса показались ему знакомыми. Он толкнул дверь. Комната оказалась пуста. Пуст был и вращающийся стул Мидж. Звуки шли сверху. Он поднял глаза на видеомониторы, и у него закружилась голова. Одна и та же картинка смотрела на него со всех двенадцати мониторов наподобие какого-то извращенного балета.

Он делает то, на что запрограммирован, а потом исчезает. Фонтейн сурово смотрел на Джаббу: - И на что же запрограммирован этот червяк. - Понятия не имею, - сказал Джабба.


Мидж вздохнула: - А что еще это может. - Это может быть не вашим делом! - раздался зычный голос у них за спиной. Мидж от неожиданности стукнулась головой о стекло. Бринкерхофф опрокинул директорский стул и бросился к двери. Он сразу же узнал этот голос.

Что же я делаю. - подумал Бринкерхофф. Мидж подошла к принтеру и, забрав распечатку очередности задач, попыталась просмотреть ее в темноте. - Ничего не вижу, - пожаловалась.  - Включи свет. - Прочитаешь за дверью.

 Чатрукьян мертв. - Да неужели. Ты сам его и убил. Я все. - Довольно, Грег, - тихо сказал Стратмор.
