Our recent musr studies on CeT 2Al10 (T=Os and Ru) reveal a clear sign of long range magnetic ordering below 28 K in both the compounds. More interestingly the frequency oscillations (or internal fields) observed below TN in CeOs2Al10 exhibit a minimum near 12 K and at the same temperature the depolarization rate exhibits jump. This is related to a charge density wave transition seen in electron diffraction at 15 K. Our bulk study on Ce(Os1-xFex)2Al10 reveals very interesting behaviour with Fe composition, x. The magnetic ordering temperatures remains almost constant up to x=0.4 and then decreases to 20 K for x=0.5, but x=0.6 sample does not order magnetically down to 1.5 K. We therefore propose here to investigate the magnetism of Ce(Os1-xFex)2Al10 (x=0.3, 0.5 and 0.6) using musr measurements on EMU.
