Ferromagnetic resonance (FMR) studies have been carried out on thin fi
lms of MnCo(x)Sb system at room temperature (RT). Exchange coupling co
nstant (A) and g-values have been evaluated from the observed spectra.
They are found to decrease with increase of Co concentration. The str
ain anisotropy field changes its sign at a concentration of x=0.18 ind
icating the spin reorientation occurring in the system. The anisotropy
fields calculated from the FMR in powder recorded at X-band and Q-ban
d frequencies also confirm the occurrence of spin reorientation.
