Beginning with a theoretical construct, UC Davis researchers have created a new compound that exhibits unusual electric and magnetic properties. Although less than 10 percent of the new material (Ca14MnSb11) contains transition metal atoms, the substance exhibits ferromagnetic properties. In other words, just a little metal gives this material a lot of pull. The magnetic character can be altered by substituting different amounts and types of metals into the formula. The compound was originally conceived by extending an electron-counting rule known as the "Zintl Concept" to transition-metal compounds. A new way of making materials, the Zintl Concept provides a theoretical starting point for more efficient synthesis of new solid-state compounds. "We are going to talk about how to rationally design new compounds," says Susan M. Kauzlarich, an associate professor of chemistry at UC Davis. "The question comes down to, how do you envision something that no one has thought about before?" Kauzlarich's research may have eventual practical applications, but it is not driven by the search for new devices. "In a technologically based society, there is a national interest in producing scientists who can make new materials," Kauzlarich says. Once these materials are invented, someone else will figure out a practical application, she says. Kauzlarich will talk about her results and research philosophy Monday, Aug. 24, 4:10 p.m., Ramada Techworld, Central Salon, Grand Ballroom Level.
