It all comes down to something called the magnetocaloric effect, wherein a changing magnetic field within a material causes it to get colder. ❋ Unknown (2010)
Giant magnetocaloric materials could have large impact on the environment ❋ Unknown (2007)
Up to now, the most promising materials are giant magnetocaloric materials. ❋ Lluís Mañosa (2010)
"If you know what is really happening in an alloy as it undergoes the magnetocaloric effect, then we can begin to think about adding other elements to get an even bigger effect - which is what we're after," he said. ❋ Unknown (2010)
Scientists must first gain a better understanding of a phenomenon called the giant magnetocaloric effect, in which a changing magnetic field in a material causes its temperature to drop precipitously. ❋ Unknown (2010)
More information: The scientists 'study, "Delocalization and hybridization enhance the magnetocaloric effect in Cu-doped Ni2MnGa," was published in Physical Review B 79 235127 ❋ Unknown (2010)
The alloy boasted some of the sought-after requirements: It had a huge magnetocaloric effect at room temperature. ❋ Unknown (2010)
Here we show that the application of a moderate hydrostatic pressure to a magnetic shape-memory alloy gives rise to a caloric effect with a magnitude that is comparable to the giant magnetocaloric effect reported in this class of materials. ❋ Lluís Mañosa (2010)
To that end, various researchers have become particularly interested in alloys that display a giant magnetocaloric effect, which is exactly what it sounds like - an enormous shift in temperature when magnetic fields are manipulated. ❋ Unknown (2010)
Although the magnetocaloric effect was discovered more than 100 years ago, scientists have only recently eyed it as a way to develop solid-state refrigerators. ❋ Unknown (2010)
Roy has spent the last few years uncovering the secrets of the phenomenon by studying alloys that experience a pronounced magnetocaloric effect. ❋ Unknown (2010)
There've been successes over the years, but no big advances that put the magnetocaloric effect within reach of consumers. ❋ Unknown (2010)
The magnetocaloric effect could also cool laptops more efficiently than battery-draining fans, serve as the refrigerant in vehicle air conditioners, and be used in industrial refrigeration. ❋ Unknown (2010)
Their work doesn't explain why nickel-manganese-gallium doped with copper boasts a huge magnetocaloric effect. ❋ Unknown (2010)
Once understood and harnessed, the giant magnetocaloric effect could be used not only in fridges, but also in applications such as laptops and vehicle air conditioning units. ❋ Unknown (2010)
"If you know what is really happening in an alloy as it undergoes the magnetocaloric effect, then we can begin to think about adding other elements to get an even bigger effect - which is what we're after," says Roy. ❋ Unknown (2010)
Jeff Kortright (left) and Sujoy Roy with an an endstation for soft x-ray resonant magnetic scattering and spectroscopy, which the scientists used at the Advanced Light Source's beamline 4.0.2 to learn more about the magnetocaloric effect in alloys. ❋ Unknown (2010)
"The focus of my group is on magnetocaloric materials, which employ a magnetic field-driven change of state to provide a cooling effect," Sandeman said. ❋ Unknown (2010)
Southern Illinois University who were using a nickel-manganese-gallium alloy with added copper, and getting a huge magnetocaloric effect at room temperature. ❋ Unknown (2010)
Much of the focus is on alloys that exhibit not just any magnetocaloric effect, but a "giant" magnetocaloric effect, so named because they exhibit a large entropy change. ❋ Unknown (2010)
