Picosecond Spin Seebeck Effect in Magnetic Insulators
… (SSE) refers to spin current generation in a magnetic insulator/non-magnetic metal heterostructure due to a thermal gradient and most SSE experiments typically use an electric current as heat source. This study uses Terahertz (THz) time-domain emission spectroscopy where a femtosecond laser …

Thermal, Magnetic, and Electrical Properties of Thin Films and Nanostructures: From Magnetic Insulators to Organic Thermoelectrics
… of techniques and instrumentation used in magnetic, thermal, and electrical property measurements of thin films and nanostructures. The understanding of trapped-flux induced artifacts in SQUID magnetometry of large paramagnetic substrates allows for the resolution of increasingly small …

Topological Transport Effects and Pure Spin Currents in Nanostructures
… to infer the properties of a multitude of magnetic systems. In turn, this allows us to push the understanding of transport phenomena in magnetic materials. The first part of this work is focused on the magnetoresistance observed in spin Hall active metals in contact with a magnetic …

Magneto-thermal Transport and Machine Learning-assisted Investigation of Magnetic Materials
… including phonons, charge carriers, and magnetic excitations. In most materials, thermal transport can be understood as the flow of phonons and charge carriers; magnetic heat flow is less well-studied and less well understood. Recently, the concept of the flat band, with a vanishing …

Structural and Magnetic Phases in Pressure-Tuned Quantum Materials
… exploring the phase diagrams and properties of magnetically ordered insulators, to add understanding to several areas of current interest in condensed matter research. It shows the versatility of pressure as an experimental technique for exploring material properties free from complicating …

Heat, Charge and Spin Transport of Thin Film Nanostructures
… and thermal conductivity of unique ferromagnetic metals. We observe improved thermopower due to the ultra-low damping of the magnon system. For spintronic and spin caloritronic applications, having a low damping is important for device engineering and allows for long spin lifetimes. …

Growth and Characterization of Polycrystalline Rare-Earth Iron Garnet Films and Heterostructures
… iron garnets, a class of insulating ferrimagnetic oxides, are particularly well suited to this application as the anisotropy, magnetization, magnetostriction, and damping can be easily controlled through selection of rare-earth ion and substrate. Previous work on garnets has focused on …

Magnetism in Two-Dimensional van der Waals Materials
… semiconductors, superconductors, and topological insulators. These few-atom-thick sheets can be restacked into endless combinations of artificial heterostructures with atomically sharp interfaces that can be thought of as fundamentally new quantum materials. For over a decade, however, magnetism …

Emergent Critical Phases in Strongly Correlated Low-Dimensional Magnetic Systems
… and highly fertile collection of van der Waals magnetic insulators known as transition metal phosphorous trichalcogenides, denoted as *TM*P*X*<sub>3</sub> (*TM* = Mn, Fe, Ni, *X* = S, Se). These compounds have proven to be ideal examples where structural, magnetic and electronic properties …
