Local electromagnetic properties of magnetic pnictides: A comparative study probed by NMR measurement
M. Majumder, K. Ghoshray, A. Ghoshray +2
75As and 31P NMR studies are performed in PrCoAsO and NdCoPO respectively. The Knight shift data in PrCoAsO indicate the presence of an antiferromagnetic interaction between the 4f…
Evidence of structural phase transition in superconducting SmFeAsO_(1-x)F_x from 19^F NMR
M. Majumder, K. Ghoshray, C. Mazumdar +4
We report the resistivity, magnetization and 19^F NMR results in polycrystalline sample of SmFeAsO_(0.86)F_(0.14). The resistivity and the magnetization data show a sharp drop at 4…
Anisotropic spin-fluctuations in SmCoPO revealed by 31^P NMR measurement
Mayukh Majumder, K. Ghoshray, A. Ghoshray +2
31^P NMR spectral features in polycrystalline SmCoPO reveal an axially symmetric local magnetic field. At low temperature, the anisotropy of the internal magnetic field increases r…
Study of electron spin dynamics in grain aligned LaCoPO: an itinerant ferromagnet
M. Majumder, K. Ghoshray, A. Ghoshray +2
139La NMR study was performed in grain aligned (c|| H0) sample of LaCoPO and polycrystalline LaFePO. Knight shift is isotropic and temperature independent in LaFePO. It is strongly…
Crossover of the dimensionality of 3d spin fluctuations in LaCoPO
M. Majumder, K. Ghoshray, A. Ghoshray +3
dc magnetization and 31^P spin lattice relaxation rate in the polycrystalline sample of LaCoPO suggest a spin fluctuation dominated ferromagnetically ordered state. Moreover, NMR d…
