Magnetic materials

Definition

Magnetic materials are materials studied and used mainly for their magnetic properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the intrinsic angular momentum, or spin, of its electrons. A material’s response to an applied magnetic field can be characterized as diamagnetic, paramagnetic, ferromagnetic or antiferromagnetic.

    Single molecule magnets have demonstrated promise for information storage, molecular spintronics and quantum computing, but are limited by their low operational temperatures. Here, Popov and coworkers prepare a SMM with a high blocking temperature of 18 K by trapping two lanthanide ions with a single-electron bond inside a fullerene.

    Blatter’s radicals are highly valuable stable organic free radicals, comprising a heterocyclic ring system functionalized with a heteroaryl or alkyl group at the C-3 position. Here, the authors report a synthetic strategy to obtain Blatter’s radical substituted with an amine and amide group.

    Cooperative electronic properties that arise purely from carbon π-electrons can lead to unconventional superconductivity and quantum magnetism. New packing architectures have now been established in two caesium-intercalated polyaromatic hydrocarbons, CsPhenanthrene and Cs2Phenanthrene, both strongly correlated multi-orbital Mott insulators. The frustrated magnetic topology in CsPhenanthrene also renders it a spin-½ quantum spin liquid candidate.

    The use of nanoscale sensors capable of detection of biological parameters is of great interest in diagnosis. Here, the authors use experimental and theoretical methods to develop a nanodiamond sensor with nitrogen vacancy defects for detection of pH and redox in a microfluidic device.

    Disentangling the chemistry and physics behind reported unconventional superconductivity and exotic magnetism in alkali-intercalated PAHs has remained problematic due to the lack of phase-pure samples. Two synthetic pathways have now remedied this issue, facilitating studies of cooperative electronic properties based on carbon π-electrons.

    For more than a decade, single-molecule magnets have relied on multinuclear transition metal clusters and lanthanide compounds. Now, a mononuclear, two-coordinate iron(I) complex has shown that single transition metals can compete with the lanthanides when certain design principles from magnetochemistry are borne in mind.

    Magnets are often electrically activated, but recent research has demonstrated various schemes that can control magnetization using light and photocarriers. Nature Photonics spoke to Petr Němec and Tomas Jungwirth about their recent work on a polarization-independent optical-torque approach.
