Magnetic Studies at high pressures
Of all the models mentioned, the one that comes closest to explaining the high pressure data on I and II is that due to Zimmermann and König (6). The model now proposed is an extension of a model that has become possible due ... -
Magnetic, Electrical and Structural Properties of Doped Manganite, Ferrite and Nickelate Perovskites
Multifunctional materials with novel magnetic and electric properties have attracted intense research interest due to prospects in technological applications as well as understanding of fundamental physics. Perovskite ... -
Magnetically arrested advective accretion flows around black holes and their implications to ultraluminous X-ray sources and blazars
Black hole (BH) accretions are very powerful sources of energy in the universe. In accretion phenomena, the surrounding gas spirals down towards the central BH and forms a disc or quasi-spherical structure based on the ... -
Magnetically powered helical nanoswimmers
From flocking birds to migrating cells, ‘active matter’ is ubiquitous in the natural world. Almost all known life forms are based on self-propelled entities working collectively to create large-scale structures, networks, ... -
Magnetisation, Phases & Phase Transitions in Frustrated and Unfrustrated XY Model
(2018-02-23)Through our whole work we study the XY model with all its entirety, a particular spin model where spins are confined in a plane. We try to bring out a good understanding of this model with all different types of phases and ... -
Magnetism and exchange in the layered transition metal thiophosphates and their solid solutions
It was mentioned in the Introductory Chapter that changes in the magnetic behaviour of the intercalation compounds of the transition metal thiophosphates depend crucially on the magnetism of the host lattice. Hence an ... -
