| 摘 要： | We investigate the structural,static magnetic and damping properties in two Mn-deficient magnetic Weyl semimetal Co-Mn-Ga(CMG) alloy films,i.e.,Co55Mn18Ga27(CMG1) and Co50Mn18Ga32(CMG2),which were epitaxially grown on MgO(001) substrates.CMG1 has a mixing phase of B2 and L21,larger saturation magnetization(Ms ～760 emu/cm3),stronger in-plane magnetic anisotropy.CMG2 has an almost pure B2 phase,small...
