The concept of a cyclotron-resonance maser (CRM) with a ferrite loading incorporated in its waveguide is proposed. The CRM interaction occurs between the rotating electron beam and the em wave propagating along a longitudinally magnetized ferrite medium. The ferrite anisotropic permeability resembles the CRM susceptibility in many aspects, and particularly in their similar response to the axial...

Glycine assisted self-combustion method resulted in fabrication of cobalt-manganese ferrite substituted by zinc ( Zn ) element. The as-synthesized Co-Mn was subjected to heat treatment at 600?C and 800?C for 2h. Effects on the structural, morphological, surface magnetic properties ZnCoMn were studied. These characterized using various techniques including TGA-DTGA, FTIR, XRD, SEM, EDX, TEM VSM....

We report the synthesis and characterization of ferrite nanocrystals which exhibit high crystallinity and narrow size distributions. The three types of samples including Zn ferrite, Mn ferrite, and Mn-Zn ferrite were prepared via a non-aqueous nanoemulsion method. The structural, chemical, and magnetic properties of the nanocrystals are analyzed by transmission electron microscopy, X-ray diffra...
