The solid state magnetic refrigerating machines operating the body is subject to ac magnetic field. Therefore магнитокалорические materials which will be used as a working body,Must have certain магнитокалорическими properties. First of all, in the material should be a giant магнитокалорическии effect in an alternating magnetic field.Магнитокалорические properties materials in constant and variable magnetic fields may be significantly different from each other.The reasons for this may be long-term relaxation processes and гистерезисные effects.Large relaxation times Гистерезисные effects result in the irreversible nature of phase transitions in a certain area of temperatures and magnetic fields,That could affect the магнитокалорических properties materials into a variable magnetic fields.
