Comme les neutrons sont des particules \u00e9lectriquement neutres, ils peuvent p\u00e9n\u00e9trer profond\u00e9ment dans les mat\u00e9riaux et nous aider \u00e0 mieux comprendre leur structure atomique. Et comme les neutrons interagissent avec les champs magn\u00e9tiques, ils constituent des outils essentiels pour sonder les propri\u00e9t\u00e9s magn\u00e9tiques souvent inhabituelles des mat\u00e9riaux quantiques qui, en retour, influencent leur comportement \u00e9lectronique, comme la supraconductivit\u00e9 (un \u00e9tat o\u00f9 le courant \u00e9lectrique circule sans r\u00e9sistance). Plusieurs boursiers du CIFAR sont d\u2019\u00e9minents sp\u00e9cialistes de la diffusion des neutrons et font progresser son application, tout en d\u00e9finissant les politiques et les infrastructures associ\u00e9es \u00e0 cette technique.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">En gros, il y a deux cat\u00e9gories de techniques de diffusion des neutrons : la <\/span><em><span style=\"font-weight: 400;\">diffraction des neutrons<\/span><\/em><span style=\"font-weight: 400;\"> (ou <\/span><em><span style=\"font-weight: 400;\">diffusion \u00e9lastique des neutrons<\/span><\/em><span style=\"font-weight: 400;\">), qui permet de d\u00e9terminer la distribution spatiale magn\u00e9tique; et la <\/span><em><span style=\"font-weight: 400;\">diffusion in\u00e9lastique des neutrons<\/span><\/em><span style=\"font-weight: 400;\">, qui permet de sonder les fluctuations et excitations magn\u00e9tiques, ainsi que d\u2019autres propri\u00e9t\u00e9s dynamiques.
