Two-dimensional (2D) magnetic semiconductors exhibit unique combination of electronic and properties, holding great promise in potential applications such as spintronics magneto-optics. However, many them are air-sensitive, their properties can be significantly altered upon exposure to air. Here, we showed an optical spectroscopic investigation the effects air-degradation on few-layered van der...

We investigate the Kerr and magneto-optical effects for a probe laser field with two orthogonally polarized components, propagating in cold Rydberg atomic gas an inverted-Y-type level configuration via double electromagnetically induced transparency (EIT). Through approach beyond both mean-field ground-state approximations, we make detailed calculations on third-order nonlinear optical suscepti...

an attempt is made for the first time to solve the quadratic and cubic model of magneto hydrodynamic poiseuille flow of phan-thein-tanner (ptt). series solution of magneto hydrodynamic (mhd) flow is developed by using homotopy perturbation method (hpm). results are presented graphically and the effects of non-dimensional parameters on the flow field are analyzed. the results obtained reveals ma...

We present a novel setup to measure the transverse magneto-optical Kerr effect in extreme ultraviolet spectral range based on fiber laser amplifier system with repetition rate between 100 and 300 kHz, which we use element-resolved demagnetization dynamics. The is equipped strong electromagnet cryostat, allowing measurements 10 420 K using magnetic fields up 0.86 T. performance of our demonstrat...
