    Can anybody explain in a few words what the "spin glass" is ? Can a material that exhibits a magnetic hysteresis (ferromagnetism) at both 5 K and 300 K be in a way a "spin-glass" also ? As recently, we have measured a material that despite the fact it is exhibiting a magnetic loop at any temperature between 5 K and 300 K, with some shifts in the magnetization for the different tempartures, it shows different curves for the magnetization versus temperature at field-cooled and zero-field-cooled conditions, with a "transition temperature around 20 K.
