摘要:

我们测量了多铁性CoCr_2 O_4在高达14 T的磁场中的磁化强度和比热。高场磁化强度的测量表明在T* = 5 - 6 K有一个新的相变。在15 K时,T* 和锁定转变之间的相位的特征在于磁不可逆性。在较高的磁场下,不可逆性增加。比热测量证实了在T* 处的转变,并且还显示了不可逆行为。我们构建了CoCr 2 O 4的场-温度相图。

英文摘要:

We have measured the magnetization and specific heat of multiferroic CoCr2O4 in magnetic fields up to 14 T. The high-field magnetization measurements indicate a new phase transition at T* = 5 - 6 K. The phase between T* and the lock-in transition at 15 K is characterized by magnetic irreversibility. At higher magnetic fields, the irreversibility increases. Specific-heat measurements confirm the transition at T*, and also show irreversible behavior. We construct a field-temperature phase diagram of CoCr2O4.
