Structural Distortions in the Spin Ladder Compounds Ba2CuTe1-xWxO6
Ba2CuTeO6 has garnered considerable interest as the combination of stacking sequence and Cu2+ displacements lead to a magnetic geometry that reproduce the effects of a spin... -
Continued studies of materials in the BiFeO3-KNbO3 solid solution
In recent years there has been a resurgence in research dedicated to ferroelectric materials primarily due to the combination of the requirement for Pb-free replacements for... -
Modulation in Molecular Materials - Variable Temperature
Modulation occurs when there is ordering on two (or more) length scales. When the ratio of these is an integer, the modulation is said to be commensurate, i.e. one ordering is... -
Interplay of magnetism and superconductivity in the iron-based spin ladder Ba...
Iron-based superconductors (FeSCs) have been an essential research area in condensed matter physics. Spins of iron sites forming a long periodic configuration, called the... -
