摘要：

Cantilever detected electron spin resonance (ESR) technique is combined with a precise rotation stage for angle-dependent ESR study of a tiny single crystalline sample on the order of 1 mu g. Generally speaking, sample rotation in transmission-type ESR measurement is quite difficult. However, high angle resolution Delta 0(min) similar to 0.2 degrees and compact design of our stage allow in situ sample rotation in strong magnetic fields at low temperatures. As a result, a systematic study of ESR spectra for different field orientations can be easily obtained without sample extraction from a cryostat. As an example, angle-dependent ESR study of Co Tutton salt in the millimeter wave region is demonstrated at liquid helium temperature. (C) 2012 Elsevier Inc. All rights reserved.
