Torsion-free crystallographic groups with indecomposable holonomy group II. [PDF]

, 2004
Let K be a principal ideal domain, G a finite group, and M a KG-module which is a free K-module of finite rank on which G acts faithfully. A generalized crystallographic group is a non-split extension C of M by G such that conjugation in C induces the G ...

Tuning of calcite crystallographic orientation to support brachiopod lophophore [PDF]

, 2018
Organisms exert exquisite control on mineral formation by tuning structural and material properties to meet functional requirements. Brachiopods are sessile marine organisms that filter feed via a large lophophore which is supported by a delicate calcite

Crystallographic and magnetic identification of secondary phase in orientated Bi5Fe0.5Co0.5Ti3O15 ceramics [PDF]

, 2011
Oxide materials which exhibit both ferroelectricity and ferromagnetism are of great interest for sensors and memory applications. Layered bismuth titanates with an Aurivillius structure, (BiFeO3)nBi4Ti3O12, can possess ferroelectric and ferromagnetic

Relationship between magnetic domain configuration and crystallographic orientation in a colossal magnetoresistive material

, 2010
We investigated the relationship between the magnetic domain (MD) configuration and crystallographic orientation in a colossal magnetoresistive (CMR) material La0.69Ca0.31MnO3 in which anisotropic magnetoresistance (AMR) was observed as well.
