Scientists have observed, quantified and created a new theoretical model of the coupling of two forms of collective atomic excitation, known as magnons and phonons in crystals of the antiferromagnet manganite (Y,Lu)MnO3, a mineral made of manganese oxide and rare-earth elements called yttrium (Y) and lutetium (Lu). This study could provide an important breakthrough for solving a 100 year old physical problem, and deepen our knowledge of an interesting class of materials called multiferroics, suggests a new report.
