The relationship between field-cooled and zero-field-cooled susceptibilities of some ordered magnetic systems
TL;DR: In this paper, the irreversible field-cooled (FC) and the zero-field cooled (ZFC) magnetic susceptibilities of one ferrimagnetic and three ferromagnetic systems, measured at different applied magnetic fields, were analyzed and it was shown that the irreversibility indicated by the difference between the FC and ZFC susceptibilities arises from magnetic anisotropy.

A First-Order Phase Transition Induced by a Magnetic Field
TL;DR: In this article, an electronic phase transition of the first order, which can be caused by an external magnetic field, was discovered in Nd 1/2 Sr 1 /2 MnO 3, where the hysteretic field region was observed to depend critically on temperature and to drastically expand with a decrease of temperature.
