LOW TEMPERATURE MAGNETIC PROPERTIES OF Nd₂Fe₁₄B SINGLE CRYSTAL

Magnetic anomaly was observed in Nd₂Fe₁₄B single crystal below 150K. Temperature dependences of magneto-crystalline anisotropy constants K₁ and K₂ has been studied. Such anomaly observed in Nd₂Fe₁₄B can be interpreted by temperature dependences of anisotropy constants K₁ and K₂.
