Field-induced magnetic states in holmium tetraboride
... plateau at M/Msat = 13 , with further, less pronounced features occurring at M/Msat ≈ 49 and 35 [20]. Significant theoretical work using Heisenberg [21,22] and Ising [23–25] spins has been used to model a variety of members of the RB4 family with many finding a plateau occurring at M/Msat = 13 , whi ...

... Most geologists think that moving charges looping around within Earth create its magnetic field. Because of Earth’s great size, the speed of charges would have to be less than one millimeter per second to account for the field. Another possible cause for Earth’s magnetic field is convection currents ...

Estimation of Magnetic Torquing and Momentum
... Thus, at any one time, momentum can only be dumped magnetically in two axes of freedom. This is of importance to a satellite meant to sustain three-axis pointing. In order to maintain strict pointing requirements, a satellite which can dump momentum only magnetically must be capable of storing momen ...
