Optical floating zone (OFZ) method has been applied to grow various materials for semiconducting industry applications as well as basic research on quantum materials. This article describes the OFZ method in detail and briefly introduces two recent advances in floating zone method by incorporating new techniques, namely, laser diode as optical source and high pressure environments. These developments have made it possible to grow materials that were previously challenging in conventional OFZ method and greatly expanded the range of accessible systems to search for exotic quantum phenomena.

The advent of modern synchrotron radiation facilities providing extremely intense x-rays has enabled measuring momentum-resolved spin excitation spectra of magnetic materials, which have long been exclusively accessible through inelastic neutron scattering. In this article, we briefly review the recent development of hard x-ray resonant inelastic x-ray scattering (RIXS) and discuss few examples of RIXS measurements on iridium oxides.

Quantum spin liquid is a phase of matter featured with quantum entanglement and fractionalization, and it has been sought after in condensed matter. Kitaev quantum spin liquid has been of particular interest due to the emergent quasiparticles of Majorana fermion, which is proposed as a venue for quantum computations. Recently, experimental evidences for Majorana fermion have been reported in the Kitaev quantum magnet -RuCl3. Half-integer quantized thermal Hall effect and field-angle dependent Majorana gap were experimentally observed. In this article, we review physics of Kitaev quantum spin liquid and recent advances in experiments.

The history of magnetism goes back to earlier than 600 b.c., but only in 20th century, people have started to understand it’s origin. Although the word ‘magnet’ may sound very familiar to you, it’s quantum nature and deep physics leads us to discover amazing phenomena. This article introduces recent frontiers of magnetic materials particularly focusing on ‘magnetic frustration and quantum spin liquids’ and discuss our current understanding.
