Magnetic properties below 1 °K
DOI: 10.1063/1.3061161
Some substances , for example iron and nickel, show a rather complicated magnetic behavior at room temperature. When placed in a magnetic field they show a magnetic moment which not only is a function of field and temperature, but which also depends on the history of the specimen; that is, it depends on the fields and temperatures in which the substance has been before. These materials are called ferromagnetics. One characteristic property is the occurrence of remanent magnetism, i.e., if the material is taken out of the field the moment does not fall back to zero but it goes to a certain value also determined by the history.
