Laser threshold magnetometry [PDF]
New Journal of Physics, 2016 We propose a new type of sensor, which uses diamond containing the optically active nitrogen-vacancy (NV ^− ) centres as a laser medium. The magnetometer can be operated at room-temperature and generates light that can be readily fibre coupled, thereby ...

Ultrasensitive Optomechanical Magnetometry [PDF]
Advanced Materials, 2014 A cavity optomechanical magneto-meter operating in the 100 pT range is reported. The device operates at earth field, achieves tens of megahertz bandwidth with 60 μm spatial resolution and microwatt optical-power requirements. These unique capabilities may have a broad range of applications including cryogen-free and microfluidic magnetic resonance ...

Tunability of the spin reorientation transitions with pressure in NdCo5 [PDF]
, 2020 We present pressure-dependent magnetization measurements carried out in the domain of the spin reorientation transitions (SRTs) of a NdCo5 single crystal. The application of a hydrostatic pressure leads to a shift in the SRTs to higher temperatures. This
