![]() | Mattis, Daniel C. | Magnetic susceptibilities of finite Ising chains in the presence of defect sites | Any antiferromagnet with zero net magnetic moment exhibits limited response to an external homogeneous magnetic field. This changes dramatically in the presence of defect sites, even those that carry no spin. We examine the excess susceptibilities, longitudinal and transverse, due to one or more d... | Antiferromagnets; Defects; Ising chain; Longitudinal field; Transverse field | 2007-12 |
