Heat capacity measurements reveal an event at 78.3 K corresponding to ordering of antiferromagnetic state.

The high temperature magnetic state is paramagnetic, while the low temperature state is an antiferromagnetic state known as a spin-density-wave.

One demonstration of ultrafast processes is the switching from collinear antiferromagnetic state to spiral antiferromagnetic state in CuO under excitation by 40 fs 800 nm laser pulse.

Whereas DPPH is normally a paramagnetic solid, it transforms into an antiferromagnetic state upon cooling to very low temperatures of the order 0.3 K . This phenomenon was first reported by Alexander Prokhorov in 1963.

Terbium has a simple ferromagnetic ordering at temperatures below 219 K . Above 219 K, it turns into a helical antiferromagnetic state in which all of the atomic moments in a particular basal plane layer are parallel, and oriented at a fixed angle to the moments of adjacent layers.

In collaboration with Chetan Nayak and Michael Freedman of Microsoft Research, Das Sarma introduced the \ nu = 5 / 2 topological qubit in 2005, which has led to experiments in building a many-body effects and electron-electron interaction in semiconductors, canted antiferromagnetic states in quantum Hall effect, various spin transistor systems, magnetic polaron theory of diluted magnetic semiconductor, coupled spin qubits in semiconductor quantum dots, theory of quantum decoherence of localized electron spins in solids, central spin decoherence problem, spectral diffusion of electron spins in solids, dynamical decoupling and quantum control, quantum transport theory in low dimensional semiconductors, bilayer quantum Hall systems, and realistic solid state effects in the fractional quantum Hall effect phenomena.
