我们利用电阻-温度和磁阻测量来绘制铒单晶的b轴磁相图。磁相变被识别为电阻率数据中的斜率变化，在恒定施加磁场沿着的b轴。在零场条件下，我们观察到大约19 K，22 K，42 K，48 K，53 K和87 K的跃迁。这些转变温度随外加磁场（H）的变化关系使我们能够绘制出铒单晶沿着b轴的H-T相图。我们观察到，零场42 K和87 K的转变没有显着的磁场依赖性，而在48 K和53 K的零场转变是高度依赖于磁场。最近，Jehan等人利用中子衍射和磁化测量方法建立了铒的a轴磁相图。我们利用他们的数据提供了有关相图某些区域磁结构的信息。
We have used resistance versus temperature and magnetoresistance measurements to construct the b-axis magnetic phase diagram of single-crystal erbium. The magnetic phase transitions are identified as slope changes in resistivity data at constant applied magnetic fields along the b-axis. At zero field we observe transitions at about 19 K , 22 K, 42 K, 48 K, 53 K , and 87 K . The dependence of these transition temperatures as a function of applied magnetic fields ( H) allowed us to construct an H - T phase diagram of single-crystal erbium along the b-axis. We observe that the zero-field 42 K and 87 K transitions do not have significant magnetic field dependence whereas the zero-field transitions at 48 K and 53 K are highly field dependent. Recently, Jehan et al have constructed the a-axis magnetic phase diagram of erbium using neutron diffraction and magnetization measurements. We have utilized their data to provide information concerning the magnetic structure in some areas of our phase diagram.
