- Abstract
- Unusual negative remanent magnetization (NRM) behavior is examined in a single-domain particle with two uniaxial anisotropies. NRM occurs in a narrow window of the parameters, which include the direction of the applied magnetic field and the angle and relative strengths of the two uniaxial anisotropies. However, these parameters are not independent of each other because changes occur in the angle between the two uniaxial anisotropies through their interactions. It is found that the anisotropy interactions are stronger at smaller crossing angles and at greater relative strengths of the two anisotropies, resulting in subsequent changes in NRM behavior.
